This is a repost of an article that I found at http://litemind.com/sunk-cost-bias/
I see many way where this describes some bad decisions that are made in Network Marketing and MLM.
How many people do you know that stay in a non-profitable program just because they already sank money into it?
The sunk cost bias is a thinking trap that not only slows down personal improvement efforts, but one which can make people literally waste their whole lives on — something I’ve seen happening with disturbing regularity. The good news is that, like most thinking traps, the biggest step you can take to overcome it is by simply becoming aware of it.business
